AM263X-MCAL-SDK: AM2634 : MMC0 interface - sdk exmple is not working in custom hardware

Part Number: AM263X-MCAL-SDK
Other Parts Discussed in Thread: AM2634

Hi,

 

We have designed custom hardware for AM2634 for our project from the reference of the AM2634 control card (EVB) design files. But the only change is that we have replaced the SD card with EMMC, 16GB.

as we know, AM2634 has only a 4-bit MMC0 interface; we had connected 4 data lines to EMMC. 

Kindly, confirm this connection of EMMC with AM2634 works?

then 

We were testing the mmc interface available in AM2634. We have made custom hardware for this purpose while trying to program it using CCS it is getting stuck at the driver initialization point. I am ataching the debug window output and the relevant parts of the schematics. In the actual harware R56, R45, R35, R30,R29, R36,R44 are mounted and R58,R49,R37,R32,R31,R38,R46,R54 are not mounted
